Did you play the Japanese version of Koichi? If so, can I ask you if he will redeem himself in his own route? Or is he still a cheater and a scumbag? I'm really curious, because I hate him with a passion in the other routes. (I saw that he seems rather popular in the Characters Ranking, so I wonder why. xD)

Yes.He is a really disagreeable man by other characters routes.But it's misunderstanding.He is just poor at an endearment.I guess it's one of his popularity.I'm sure you can understand it if you play his route.
